Programming each part with a different progressive serial number

  we need to assign an unique 16 bit serial number to our production SMT32F051C6T6 parts.
I can't do this by calculating it from the 96 bit UID read from the Unique device ID register because I think that in this case I won't be sure that there will not exist two parts with the same 16 bit. 

This 16 bit serial number will be saved in a flash location and then read by the firmware.

The only idea I have is to write a special software that, every time a part is to be programmed, reads the original .hex file and overwrites the relevant location with a 16 bit number that is then incremented for the next programming operation. Then the obtained hex file is used with a standard programming utility such as ST-Link Utility. Probably I'll use the command-line version in order to automate this process.

Anyway, this is a quite common need so I suppose that maybe some tools of this kind already exist, are you aware of them?

Thanks in advance.
Best regards,
